I went for a ride after work on Monday. On my way back home, about 5 miles out, I felt a “bump” in my rear wheel. I got off the bike and noticed a bulge in my rear tire. It pushed the tire off to the side a bit. There was no cut in the tire and nothing imbedded in it. I got back on and headed home…a little nervous. I took the downhills a little slower. When I racked my bike I rotated my tire so the bulge was at the top. I figured the tire would go flat in a few hours and that way I knew where to look for whatever caused the problem. I went inside and cleaned up. About 45 minutes after racking my bike I heard a loud bang come from the garage. My dog went wild! I went to check it out and sure enough, my tire had exploded!

So what do you think caused the tire to bulge like that in the first place? And why/how did the tire explode if there wasn’t a cut in it? Anyone have any insight into what might have happened? It kind of scares me to think it might have exploded like that while I was riding in traffic.
